Loveland Castle

Location: Loveland, Ohio

Harry built the entire castle himself, using 2,600 sacks of cement and 32,000 quart milk cartons, for forming concrete bricks, 54,000 five-gallon buckets of dirt, and 56,000 pail-fulls of stone. He also built a secret room into the castle that wasn’t discovered until it collapsed years after his death.

In a freak accident, Harry Andrews set himself ablaze while cooking in the castle and died two weeks later. Today, the castle is still run by the “Knights of the Golden Trail,” the youth organization established by Andrews. Unsurprisingly, it is said to be haunted.
